Am I not correct that 1.3 got backed out of chrome for the current issue? So 1.3 isn't even there now... Which breaks anything that explicitly requires 1.3. My fix would support all cases and not break anything. Unless I missed something?

Nothing can require 1.3, since 1.3 isn't finished yet. They were doing interoperability testing with a draft version of TLS 1.3, and nobody should require a draft version of TLS 1.3 without having a fallback to TLS 1.2.
